| 摘 要： | 从理论上推导了球面波作为参考光和读出光时体全息存储的相对衍射效率和晶体旋转角度之间的关系，对得到的衍射效率的理论公式进行了数值模拟，并且对模拟的结果进行了分析。将得到的结论与平面波条件下的结论进行对比，结果表明，球面波系统的存储容量更高，角度选择性更好，并且有利于系统的小型化。

| Abstract: | In this paper the relation between relative diffraction efficiency and rotation angles of the photorefractive crystal with spherical waves as reference and retrieving beams is theoretically deduced, then the equations of diffraction efficiency are numerically simulated and the results of simulation are also analyzed. The different results are analyzed, and the conclusion that the storage system with spherical waves has a larger volume, better angular selectivity and is useful for miniaturization of system is obtained. |
